Kimi K2.7 Code vs Nemotron 3 Ultra

Published LiveBench scores across all seven categories, live list pricing, context windows, and the measured cost of a point of capability — for both models, side by side.

OpenRouter + LiveBenchAll comparisonsFull leaderboard

Kimi K2.7 Code scores higher, Nemotron 3 Ultra costs less — it depends on your workload.

Kimi K2.7 Code is ahead by 1.1 points overall, and Nemotron 3 Ultra lists 29% cheaper per blended million tokens. Whether 1.1 points is worth that depends on how much a wrong answer costs you. The two cost measures disagree here, which is worth knowing: Nemotron 3 Ultra has the lower sticker price, but Kimi K2.7 Code earns each point of capability for less — $0.0545 against $0.2118 — because per-token rates do not predict how many tokens a model actually spends on a task.

Which gives better value for money, Kimi K2.7 Code or Nemotron 3 Ultra?

Kimi K2.7 Code. Cost per point divides the measured dollars LiveBench spent running the benchmark by the score it earned, so it captures something token pricing misses: a reasoning model can emit many times more tokens than its per-token rate suggests. Kimi K2.7 Code works out at $0.0545 per point and Nemotron 3 Ultra at $0.2118.

Does Kimi K2.7 Code or Nemotron 3 Ultra have a bigger context window?

They are effectively the same — 262K for Kimi K2.7 Code and 262K for Nemotron 3 Ultra.

Do Kimi K2.7 Code and Nemotron 3 Ultra support prompt caching?

Both publish a cached-input rate: $0.180 per million for Kimi K2.7 Code and $0.120 for Nemotron 3 Ultra, against full input rates of $0.706 and $0.600. On a workload with a long stable prefix — a system prompt, a tool schema, a retrieved corpus — that changes the economics more than the headline price does.

How these numbers are produced

  • Price — provider list price from OpenRouter, refreshed every 15 minutes. “Blended” is a 3:1 input:output mix.
  • ScoresLiveBench release 2026-06-25, using their own category map. Each model shows its strongest published run. A blank means “not evaluated”, never “bad”.
  • Cost per point — the measured dollars LiveBench spent on the run, divided by the score it earned.
  • “Win” — awarded only past a threshold: one full point on a benchmark score, 10% on a price, 25% on a context window. Anything tighter reports as a tie, because effort settings alone move a LiveBench score by more than that.
